I have installed ghostscript of 64 bit on my 64 bit linux machine. I am using ghost4j-0.5.0.jar to convert pdf files to tiff files. I have written a java program which will convert pdf files to tiff files. This is working perfectly fine on Windows but when i thought of moving this to linux machine i am getting the below error.
